Materials Data on OsO2F3 by Materials Project

Abstract

OsO2F3 crystallizes in the monoclinic Pc space group. The structure is one-dimensional and consists of two OsO2F3 ribbons oriented in the (0, 1, 0) direction. there are two inequivalent Os7+ sites. In the first Os7+ site, Os7+ is bonded in an octahedral geometry to one O2- and five F1- atoms. The Os–O bond length is 1.68 Å. There is three shorter (1.89 Å) and two longer (2.04 Å) Os–F bond length. In the second Os7+ site, Os7+ is bonded in a 6-coordinate geometry to three O2- and three F1- atoms. All Os–O bond lengths are 1.71 Å. There are a spread of Os–F bond distances ranging from 1.90–2.25 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one Os7+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one Os7+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to one Os7+ atom. In the fourth O2- site, O2- is bonded in a single-bond geometry to one Os7+ atom. There are six inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one Os7+ atom. In the second F1- site, F1- is bonded in a 2-coordinate geometry to two Os7+ atoms. In the third F1- site, F1- is bonded in a single-bond geometry to one Os7+ atom. In the fourth F1- site, F1- is bonded in a distorted bent 150 degrees geometry to two Os7+ atoms. In the fifth F1- site, F1- is bonded in a single-bond geometry to one Os7+ atom. In the sixth F1- site, F1- is bonded in a single-bond geometry to one Os7+ atom.
